77|This invention relates to vehicle Wheels and more particularly to Adeniountable rim attachments, although it may be employed With equal advantage for other purposes. l It contemplates more especially the provision of novel means for maintaining relatively movable members in rigid relation so as to enable the ready removal or assembly thereof. Y Y' Devices of Yknown construction have-not proven entirelyl satisfactory in that considerable difficulty vis'encountered in effecting the desired relation and lrigidity between the cooperating elements, it being very laborious to attach or remove one jmember from the other. This is vespecially true in demountable rim vconstructions employing knovvnexpedients.

Further', toarrange and maintain a rim in its desired relation with respect to a Wheel, it is highly desirable to provide siniple'and effective securing means Which yvill enable the convenient Aand ready assembling and dismantling of the rim with respect to the Wheel Without necessitating the use of tools 'or requiring any appreciable effort and time.' y

One object ofthe present invention is t-o simplify theconstruction and improve vthe operation of devices of the vcharacter'.inentioned. i

Another object is to provide improved securing meansV Which'can be readily interv posed lbetween adjacent members to maintain them iii the desired relation. v n

A further o/bJect is to provide improved means ofinerxpensive construction to facilitate convenient andA instantaneous assembling and dismantling of the relative units.

A still further object is to provide securing means simultaneously operable by a single -means to selectively effect vengagement and disengagement thereof.

' Other objects and advantages Will appear from` the following description of an illusytrated embodiment ofthe presentginvention. Y i

In the drawings Figure 1 is a view in elevation of a Wheel embodying features of the present invention.

Figure -2 Vis a sectional view taken substantiallyalong line H-II of Figure 1.

Figure l is a view taken substantially along line IV-IV of Figure 1.

Figure 5 is an enlarged detail of an engaging lug shown in Figure 1.

Figure 6 is an enlarged detail similar to Figure 5 showing a modified embodiment of the present invention.

In the particular embodiment of the present invention Which has been herein selected for illustration,` the related units coin- 'prise a vehicle Wheel 10 of standard construction, having associated therewith the usual deinountable tire rim 11 adapted to carry the customary tire 12. In order' to maintain the related adjacent units, in this instance the Wheel 10 and rim l1, in rigid relation so as to permit the ready relative attachment or removal thereof, means are provided to be simultaneously and selectively actuatable by a single movement as Will hereinafter appear'.

'In the structure shown, the means coniprises a plurality of engagingA lugs 18 equally spaced about the periphery of the Wheel, they being slidable in a radial direction Within suitable guides 14 secured to the Wheel 10 adjacent the periphery thereof.

Vrlhe engaging lugs 13, in this instance, are stamped from sheet metal to present a trapezoidal cross section 15 terminating rin laterally extending [langes 16 which cooperate with the correspondingly shaped grooves defined by the overlapping edges 17 of the guide members 14. The guide members 14 are secured to the' Wheel 10 by means` of any appropriate.fasteners (notl shown), the grooves thereof extending in a radial direction with respect to the axis ofthe Wheel.

' Actuating means, in this instance a ring 18 preferably of metal having a substantially rectangular cross section, is rotatively associated With the Wheel 10 by means of the anchoring guides 19 secured in this instance to the spokes of the Wheel to slidably receive the ring 18 Which preferably is of such size as to have the periphery thereof in proximity to the extremities of the engaging lugs 13. The lugs 13 are operatively connected to the ring 18 by means of a link 20 individual to each lug 13, the former having the free extremities thereof apertured as at 2l to receive freely fitting pins 22 whereby the links are pivotally associated With the ring 18 and the engaging lugs 18. Thus it will be apparent that rotary movement of the yring 18 willsimultaneously move all the lugs 13 radiallyV Within their guides` v14 to either lengage or disengage the rim 11 depending upon the direction in which 1the Wheel is rotated. l

. h The rim 11is preferably provided with imeans for receiving the engaging -lug -1'3 so as to prevent relative .movementfoetvveentheV Wheel and rim. The Iin'e'an's"in this instance comprises a pair oi space'd projections 23 'and 24 adapter'l 'toy receivethefengaging lugs 13 theiebetvvee'mfit bei'ng obvious that jthe Vprojections ma'yfbfe integrally or otherwise secured to the rii'n`11. lt Vis to 'be notedtha't the projections may be dispensed 'with' in that V'the'.i'i'iction between the engaging lugs 13 Vand vthe rim inay be V'relied yupon -to vprevent relative "movement therebetween.
